City in Southern CA, actually called Fontana. Outdated term used to desribe the amount of rednecks who used to live there. Fontana is currently called North Mexico, due to the large number of mexicans who now live there.

The word combination of the places Fontana, CA and Kentucky. People who live in other, nicer areas of southern California often make fun of Fontana because of the many trailer parks, loose chickens running around, and the trailer park trash that reside there. KKK lives there, along with some low-class Mexicans and blacks. It is the backwoods of California. More recently, Fontana is experiencing urban sprawl with housing developments coinciding with high real estate prices, and chain stores and fast food restaurants that have made Fontana a better place to live. But it will never shake the reputation it is had as Fontucky.
